如果您使用的是Java 8，则可以使用

If you are using Java 8 you can use java.time API Like so :

int addWeek = 0;
if(startDate.get(WeekFields.ISO.weekOfYear()) < endDate.get(WeekFields.ISO.weekOfYear())){
    addWeek = 1;
}
long weeks = WEEKS.between(startDate, endDate) + addWeek;//Get the number of weeks in your case (52)
List<Integer> numberWeeks = new ArrayList<>();
if (weeks >= 0) {
    int week = 0;
    do {
        //Get the number of week
        int weekNumber = startDate.plusWeeks(week).get(WeekFields.ISO.weekOfYear());
        numberWeeks.add(weekNumber);
        week++;
    } while (week <= weeks);
}

[34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52,
  1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 
 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34]

请注意，您会同时获得两个年份的两个星期编号，即 2018 [34-52] 的几周，然后是 2019 [1-33]

Note that you get both week numbers from both years, weeks of 2018 [34-52], then weeks of 2019 [1-33]
